What version of O/S does PiScreen work with?

Currently, the only O/S PiScreen works at 100% is Raspbian.
There is a hack to get it working with RaspBMC, which is to copy the image from the normal display output (HDMI/RCA) to PiScreen. This makes the touch input unusable and shows video with poor quality .
We will share any updates we have of PiScreen working with other O/Ss.
